A half-century ago, the mean height of women in a particular country in their 20s was 64.2 inches. Assume that the heights of today's women in their 20s are approximately normally distributed with a standard deviation of 1.85 inches. If the mean height today is the same as that of a half-century ago, what percentage of all samples of 20 of today's women in their 20s have mean heights of at least 65.33 inches?

In the following situation, determine whether you are asked to determine the number of permutations or combinations. then do the calculation how many ways are there to pick a starting five from a basketball team of twelve members? a. permutation; ps - 2520 b. combination; 1c, - 792 c. combination: 2cs - 2520 d. permutation; ps - 95040

Any is very appreciated! (picture is provided below)not sure how to do this at all won't lie

Need now max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a) the median of max’s data is 250 b) more than half of the data points max recorded were 177 centimeters. c) a data point chosen at random is as likely to be above the mean as it is to be below the mean. d) every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.
